Subject: [dpdk-dev] [PATCH v2 01/17] net/bnxt: fix incorrect flow steering
Date: Tue,  1 Oct 2019 22:54:07 -0700	[thread overview]
Message-ID: <20191002055423.99659-2-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20191002055423.99659-1-ajit.khaparde@broadcom.com>

From: Santoshkumar Karanappa Rastapur <santosh.rastapur@broadcom.com>

When user creates a flow similar to an existing flow with just the
destination queue change, we delete the old filter and allocate a new one
with this destination queue change. We were also allocating a new L2
filter matching the same destination mac resulting in 2 L2 filters for the
same destination mac. This was causing any flow matching the destination
mac to be steered to this queue instead of the default queue.
Fixed it by deleting this stale L2 filter.

Fixes: 5c1171c97216 ("net/bnxt: refactor filter/flow")
